The shady underside of peptide sellers long before GLP-1's and routine independent testing was to promote the fallacy that peptides are fragile and have limited shelf life etc. so they could conveniently explain away bad product. Now some of the most common questions are related to storage, longevity and degradation and so many people allow themselves to get psyched out over this nonsense.
It's like people who mindlessly throw out perfectly good eggs or bread on the "expiration" date because they think there's a magical self-destruct mechanism at play.
